Abstract

L'invention concerne un dispositif pour rincer automatiquement la cuvette des WC. Le dispositif comprend un siège (5) des toilettes. Le siège (5) est pourvu d'une chambre de pression (7) destinée à expulser l'air lorsque la chambre (7) est comprimée et à aspirer de l'air lorsque la pression est relâchée. Un levier rotatif (24), monté par charnière dans une fente de montage (21) de l'ouverture et du levier d'obturation (19), pivote sur un plan vertical. Une barre de manipulation (17), dont une extrémité est pourvue d'un crochet (18), communique avec la chambre de pression (7) du siège (5) des toilettes de manière à ce que le crochet (18) de la barre de manipulation (17) pousse ou tire l'extrémité supérieure du levier rotatif (24) lors des mouvements en avant ou en arrière. Une barre de guidage (25), fixée sur un côté de l'ouverture et du levier d'obturation (19), à son extrémité supérieure, s'étend vers le bas. Un flotteur (26), installé mobile autour de la barre de guidage (25) à travers un trou d'insertion vertical (27) de manière à pouvoir être guidé par la barre de guidage (25), est pourvu dans sa partie supérieure d'une fente de guidage (28) et relié à la vanne d'obturation (4) au moyen d'un fil de raccord (30), le trou d'insertion vertical (27) se prolongeant jusqu'à la fente de guidage (28).
